Quarter-Sized Mosquitoes Really Exist

If you dislike mosquitoes, you'll really have daggers for the
gallinipper — a giant mosquito that is about 20 times the size of
a regular mosquito. It's big enough to cover a quarter.

The insect lives in low-lying areas that overflow with
water. They are native to the eastern half of North
America, but come out in large numbers when an area is hit by
heavy rain, such as in a tropical storm or
hurricane.
